FFEQEQ I 7 FAN.

Fort Payne, in the county of Dekalb and State of Alabama, have invented new and useful Improvements in Fans, of which the following is a specification. 7 r This invention relates to improvements in fans and has particular application to motor driven fans. I In carrying out the present invention, it is my purpose to provide a device of the class described which will be found espefan and wherein the fan blades may be elevated and lowered so that the distance between the fan blades and the floor of the room or other compartment in which the fan is installed may be I 1 varied. 20

It is also my features of simplicity, efficiency and durability, which may be installed and maintained at a minimum expense and which will operate effectively for its intended purose. P With the above and other objects in view, the invention consists inthe construction, combination and arrangement of parts hereinafter. set forth in and falling within the scope of the claims. j

In the accompanying drawings; Figure 1 is a view in side elevation of a fan constructed in accordance with the present invention, the same being shown as suspended from aceiling. Fig. 2 is an enlarged vertioal central sectionalview through the fan. F1 3 1s a cross sectlonal view on the line- 83 of Fig. 2 looking in the direction of the arrow. Fig. 4: is a similar view on the line lat of Fig. 2. Fig. 5 is a like view on the line 55 of Fig. 2. Fig. 6 is an enlarged vertical sectional view through the driving motor for the fan.

Referring now to the drawings in detail, 1 designates a ceiling plate which is substantially rectangular, in contour and is formed, adjacent V with openings 2 through which securing screws or bolts are adapted to pass in order to fasten the plate to the ceiling. In the present instance, an auxiliary supporting bracket 3 is suitably secured to the marginal edges with openingsa through which bolts or se- Specification of Letters Patent.

with the bolts in the openings 2 and so effectively secure the plate 1 to the ceiling. Connected with the central portion of the plate 1 5 and formed on the lower end of the tube 5 and projecting outwardly therefrom is an annular flange 6 having the under surface thereof provided, adjacent to the inner edge thereof, with an annular groove 7 Bolted or otherwise fastened to the flange 6 at theperiphery thereof and depending therefrom is anannulus 8, while formed on the lower edge of the annulus 8 and extending inwardly therefrom is a circular flange 9.

Seated upon the flange 9 within the annulus 8 is a disk 10 formed contrally with an, opening registering with the openingin the fiange9 and suitably connected to the wall of the opening in the disk 10 is a sleeve 11 projecting below the flange 9 and disposed coaxial with the tube In the present in stance, the confronting faces of the flange 9 and disk 10 are formed with cooperating tube 5 is'a shaft i l and connected with the lower end of the shaft and radiating therefrom are fan blades 15, while threaded through-the sleeve 11 and spaced apart equal distances about such sleeve are set screws 16 whereby the sleeve may be fixed to the shaft 14: to rotate therewith and revolve the same within the tube 5. In the present instance, the upper end of the shaft 14: is formed with an upwardly extending axial stem 17 and threaded onto the stem 17 is a nut 18 having the outer edge thereof formed with a groove alining with a groove in the adjacent end'of the shaft 14 to form a way designed to receive anti-friction bodies'19, the anti-friction bodies 19 engaging the inner wall of the tube 5 and acting to hold the shaft properly centered within the tube and minimize friction between the upper end of the shaft and the tube.

Suitably fastened to the upper surface of the flange 6 at one side of the tube is a spring motor 20 which is preferably in the and'depen'ding therefrom is a tube formof a clock train and includes a horizontal main shaftor arbor '21- upon which is rotatably mounted a sleeve 21 carrying a driving gear 22 working within a slot formed in the adjacent portion of the flange 6 and meshing with an annular row of teeth 23 formed on the upper surfaceof the disk" concentrically thereof. Also keyed upon the sleeve 21-is a pinion 24t meshing with a gear wheel 25 keyed upon a power shaft 26.

Surrounding the power shaft 26 is a spring 27 having the inner end thereof secured to the main'sleeve 21 is controlled through asuitable form of governor so that the mam shaft wlll rotate at a unlform speed.

In the present instance, the governor 33 embodies spring arms 34- having correspond ing ends thereof fastened to one end of the sleeve 21' and the remaining end fastened to a collar 35 surrounding the shaft 21 and capable of rotary and longitudinal movements thereon, and a collar 36 fixed upon the shaft 21 adjacent to the collar 35 between the I latter and the adjacent end of the sleeve 21. These spring arms 34 are equipped with weights 36 respectively andin the rotation "of the sleeve 21; under the action of the spring the weights 36 fly outwardly and so slide the collar 35toward the collar 36 and v in the'event of the too rapid rotation ofthe "sleeve 21 the'collar 35 will engage the collar 36 and so act, as-a friction brake to cut down the speed of the sleeve; 7 In practice, when it is desired to set the.

shaft 14 in motion so that the fan blades'15 will be rotated to facilitate the circulation of air, apull is exerted upon the lower end of the cord 30, thereby rotating the winding wheel 28 and placing the spring 27 under tension. When the cord is released, the power spring reacts, and so rotates the power shaft 26; and the sleeve 21, the governor 33 controlling the rotation of the sleeve from the spring. In the rotation of the sleeve,

the gear wheel 22 imparts movement to the.

disk 10 thereby revolving the latter upon the flange 9 and within the annulus 8 so as to rotate the sleeve 11 andthe shaft 14 connected with such sleeve. To elevate or lower the fan blades, the set screws 16 are loosened in the tube and sleeve to dispose the fan 'blades'at the-proper elevation, the set screws "and the shaft 14. moved longitudinallywith- T i v The power shaft 26'is preferably provided with a crank handle at whereby the spring may be placed undertension inthe event of failure of the cord 30 orowinding wheelf28. In the present instance, I have shownmy IIHPIOVBClTIlOiJOI driven fan as embod ed 111 a ceiling; fan andin this connectionI'wish it to be understood that the'invention in its useful application is not limited to ceiling fans as the same may be incorporated in wall fans and other stationary fans.

IvVhile I have herein shown and described, one preferred form of-jmy invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein de scribed and delineated, as modification and variation may be made within the scope 'of the claims without departlng from. the spirit I of the invention.

I claim 1'. A .fan comprising a shaft, bladesra-. diating'from one end of said shaft, sleevev encircling said shaft, an adjustable connection between said sleeve and shaft whereby," theblades may be moved toward and away from the sleeve, a disk surrounding said sleeve and fixed thereto, a flange supporting. 7

said disk, an annulus carrying said flange,

' anti friction bearings between said disk and flange and annulus, 'means supporting said annulus, a motor carried by said last means,

and driving connections between said motor and disk.

2. A. ceiling fan comprising a vertical.

-tube,:a flange on the lower end of'said tube" projecting outwardly therefrom, an annulus depending from the marginal edge ofsald flange, a flange formed on the lower edge of 7 said annulus and extending inwardly therefrom, a disk within said annulus and restmg upon the flange thereon, anti-friction bearings between said last flange and annu lus, a sleeve carried by said disk and depending below the second-named flange and co-' axial with said tube, a shaftiwithin said sleeve and extending into the tube, a con nection between said shaft and sleeve, blades radiating from the lower end of said shaft, a motor, and driving connections between said motor and disk whereby the sleeve and shaft may be rotated. v
